Cities can save energy –and money- by illuminating public spaces with LENDs, or light – emitting diodes. In December 2006, Raleigh, N.C., turned one floor of a municipal parking garage into a testing ground for LEDs (see the before- and – after photos at cree.com/LED city). The new white, brighter fixtures use 40% less electricity than the high –pressure sodium bulbs they replaced every 18 monds. Other types of LEDs are already at work in traffic lights, outdoor displays (like those in New York City’s Times Square) and stadiums; airports even use LEDs on their taxiways. If your city is still burning tax money on old lights, ask the mayor why.Lights Up Your City.
